Can we conclude that there is no TDL4 on my computer and my computer is clean?

By the way, I am not aware of the recovery ability of Dell MBR. Do you know by chance how to use it?

I don’t remember when but it did happen that I suddenly have two more local drives on my computer besides the C:. The computer generated them on its own sometime after I had only one local drive for at least two years. Are they the recovery partition you talk about?

Thank you everyone.
